angle of flight

I took off from an airport at an angle of 18° (nearest degree). At a horizontal distance of 1000m (3sf) away from where I take off there is a range of hills 300m (nearest 10m) high. If I maintain an angle of 18° show weather I will clear the range.

I took off from an airport at an angle of 18° (nearest degree).
At a horizontal distance of 1000 m away from where I take off
there is a range of hills 300 m high.
If I maintain an angle of 18°, show whether I will clear the range.

There are a number of ways to answer this question.

A 1000 C

The 300-m hill is 1000 m away.
What angle is needed to clear the hill?
